nrf5x: refactor device control transfer.

- make control transfer as part of usbd. Class driver must use
usbd_control_ API() instead of dcd_ api.
- change the signature of class driver's control_request
- allow control request complete to stall in staus stage
- move control request parser & handling to usbd.
